What is a subject matter expert?
A subject matter expert is a person with deep knowledge of a specific domain, process or tool, often abbreviated SME. In learning and development, subject matter experts provide the raw expertise that courses are built on: they know how the work is actually done, where the pitfalls are and which details matter in practice.
One note on the abbreviation: SME can also mean small and medium-sized enterprises, so in mixed company it pays to spell out subject matter expert at least once.
The subject matter expert's role in course production
Subject matter experts rarely build courses alone, and they should not have to. The strongest results come from pairing them with instructional designers: the expert brings the knowledge, the designer shapes it into something people can learn from.
- The expert shares knowledge through interviews, walkthroughs and real examples.
- The instructional designer structures the content, sets learning objectives and chooses formats.
- The expert reviews drafts for accuracy and adds the nuances only experience can provide.
- Both revisit the course over time to keep it current.
This division of labor protects the expert's time and the participant's experience. Expertise does not automatically make someone a teacher, and it does not need to.
Subject matter experts in practice for L&D teams
The biggest challenge for L&D teams is usually not finding experts but capturing their knowledge without eating their calendars. Short focused interviews, screen recordings and structured review rounds get more out of an hour than a vague request to "create a course about your area".
A learning platform with simple authoring tools helps here too. When it is easy for a subject matter expert to record a walkthrough or draft a module, knowledge sharing stops depending on heroic effort. Treat your experts' time as the scarce resource it is, and give them the shortest possible path from knowing to sharing.
FAQ: subject matter experts
How do you choose the right subject matter expert?
Look for three things: current hands-on knowledge of the topic, willingness to share it, and enough availability to review drafts. The most senior person is not always the best choice. Someone who recently learned the process often explains it most clearly, with a fresh memory of what was confusing. For critical topics, involve two experts so the review never depends on a single calendar.
Does a subject matter expert need teaching skills?
No. A subject matter expert contributes knowledge, not pedagogy. The instructional designer or L&D team shapes that knowledge into learning objectives, structure and formats participants actually learn from. Expecting experts to also be teachers slows production and burns their time. Let each role do what it does best, and the course becomes both accurate and engaging.
How much time does a subject matter expert need to invest in a course?
Less than most experts fear. With a structured process, a typical module needs a few short interviews or walkthroughs, plus one or two review rounds of the draft. Prepared questions, screen recordings and clear deadlines keep each session focused. What consumes expert time is vague requests like "create a course about your area", so make every ask specific and small.
